> The exception occurred because the UIViewParameter.java was holding on to
> it's renderer because it's a static variable. This cause a few problems:
> 1) Since WebSphere ships MyFaces in the runtime more than one application is
> using this Static variable ( unlike when JSF is bundled within the
> application ), so each application is using the same renderer.
> 2) The renderer was not being released during a restart of the application so
> one from a different classloader was being used causing the ClassCastException
> 3) Since UIViewParameter is within the API we could not just add a method to
> clean up the render, so I had to use the reflection API to make the call into
> a private static method.
> I've attached a patch for this issue. Please review and let me know your
> thoughts. I've tested this and have had a customer also verify that it
> solves the issue they were seeing.
